Everyone who has Philips Ultinon will say they are pure white.
And I have seen it in person and I agree with everyone.
I was trying to look for the lumens info from the instruction manual that come with the box or philips official website, but no luck.

Looks like there is no group buy. Not enough interest.
There is 2 buyers already check out via my website and their bulbs are going to be ship tomorrow.
If you want a set you can check out via my website.
